Trouble creating a folder via web script

mikew — Thu, 20 Nov 2008 17:21:14 GMT

I’m attempting to write a very simple proof of concept stand-alone java program that communicates directly with a remote Alfresco server (3.0b) via web scripts. The program will, hopefully, recreate a local directory structure and upload local files into it. I am running into problems, specifically

Hello Mike,
I am facing the exactly same problem. I am stuck from a long time.
I am using local server. Can you please send the solution if you got.

Your help will be highly appreciated.

Thanks in advance.

Hi Lakshya,
I did not solve this, instead had to take an entirely different tack. Instead of using webscripts, we ended up using the alfresco ftp mechanism, which seemed to work… (user with admin privileges needs to run the alfresco process for ftp to work, though…)

Thanks Mike,
I got the solution…
Actually we need to pass the details through xml.

Here is the code snippet:
URL = "http://localhost:8081/alfresco/service/api/path/workspace/SpacesStore/Company%20Home/children";
PostMethod method = new PostMethod(URL);
String filePath = "testDoc.xml";
String contentType = "application/atom+xml;type=entry";

File upload = new File(filePath);
method.setRequestHeader("name", upload.getName());
method.setRequestHeader("Content-type", contentType);

method.setRequestBody(new FileInputStream(upload));
client.executeMethod(method);
System.out.println(method.getResponseBodyAsString());

testDoc.xml
<?xml version='1.0' encoding='utf-8'?>
        <entry xmlns='http://www.w3.org/2005/Atom' xmlns:cmis='http://www.cmis.org/2008/05'>
         <title>My Picts</title>
         <summary>My Picts – Summary</summary>
          <content type="text/html">${CONTENT}</content>
         <cmisbject>
          <cmisroperties>
           <cmisropertyString cmis:name='ObjectTypeId'><cmis:value>document</cmis:value></cmisropertyString>

          </cmisroperties>
         </cmisbject>
       </entry>

Now I am checking that how I could pass the details in xml through Java.

Thanks for your reply….
Regards

Thanks for your example .

But it seems it doesn't create a space but a file. How create a space in Alfresco v3 ?

Re: Trouble creating a folder via web script

lakshya — Thu, 09 Jul 2009 09:14:41 GMT

Hello Cytrix,
For creating folder just change
<cmisropertyString cmis:name='ObjectTypeId'><cmis:value>document</cmis:value></cmisropertyString>
to
<cmisropertyString cmis:name='ObjectTypeId'><cmis:value>folder</cmis:value></cmisropertyString>

Thanks, but it only works with text files. How can I pass a PDF through the XML? I tried using Base64 but I don't know how to tell the server the file that way, any ideas?

Sorry…
I also faced the same problem
If you get the solution please do send a post with solution..

Re: Trouble creating a folder via web script

groberts — Mon, 06 Sep 2010 20:53:47 GMT

Thanks for this discussion, its helped me.

Can anyone say why I get a document instead of a folder when I try to create a folder with Firefox REST client as follows;

I POST to http://admin:admin@xxx.mydomain.org/alfresco/service/api/path/workspace/SpacesStore/Clinical%20Studies/children

with just one Header

Content-type application/atom+xml;type=entry

and a body of

<?xml version='1.0' encoding='utf-8'?>
<entry xmlns='http://www.w3.org/2005/Atom' xmlns:cmis='http://www.cmis.org/2008/05'>
<title>ThisShouldBeAFolder</title>
<summary>ThisShouldBeAFolder</summary>
<cmisbject>
<cmisroperties>
<cmisropertyString cmis:name='ObjectTypeId'>
<cmis:value>folder</cmis:value>
</cmisropertyString>
</cmisroperties>
</cmisbject>
</entry>

I see an ordinary bit of content created !

Re: Trouble creating a folder via web script

Just checked in the book, "Alfresco 3 Web Services" and the correct Atom XML to create a folder (for me in Alferesco Community 3.3g) is as follows.

(Just a bit confused as to why the recent XML posted above created a document instead of a folder)
(While I am at it, non of this is RESTful, its just like a web service !)
